My Responsibilities For Shared Sewer Line in Seattle

[Tim Garcia]

I have a rental property in Seattle. My property is up hill of my neighbor and our title states that the cost of the repairs to the sewer line are shared for the shared section of pipe that leads to the city sewer line. I do not have any immediately noticeable sewer issues, but I consulted with a sewer repair company and they said the shared pipe on the neighbor's side of the property is in need of repair. My question is, what I am responsible for paying for in this shared scenario. I assume the cost of the pipe replacement is shared, but it seems like the digging on their side of the property is going to be pretty complex because of a retaining wall they have. Is all of the digging also my responsibility? Has anyone had a similar situation? Experience in Seattle would be very helpful. Thank you!
